Location of Spark plugs on a 2004 Ford Expedition Eddie Bauer?

The 2004 Ford Expedition Eddie Bauer, like other models of that year, likely uses a 4.6L V8 engine. Spark plug location on a V8 is generally in the valley between the cylinder heads. However, *precise* location requires looking at a repair manual specific to that vehicle's engine. The plugs aren't easily accessible and often require removal of parts like the intake manifold or various covers to get to them.

Do not attempt this without a repair manual. Incorrect placement can seriously damage the engine. A repair manual (either physical or digital) will have diagrams showing the precise location of each spark plug and the steps required for their replacement. You can usually find these manuals online or at auto parts stores.

Trying to describe the location verbally is unreliable and could lead to mistakes. Using a repair manual is crucial for a safe and successful spark plug replacement.
